One of the top steps is a trigger for opening a small chamber near the bottom of the stairs containing a soul sphere and, further on, a partial invisibility. Along the southern wall is a set of stairs leading up. Cross this new bridge to pick up the blue keycard (G).Ĭross the nukage pond in the central area and enter the blue key door. This will raise the sunken center portion of this platform, and raise the bridge in the northern room. The center of the platform at this end will lower into the nukage drop in and press the switch (or do not drop in and activate the corresponding wall from the platform, because the Doom engine ignores Z difference in such cases). Quickly walk (or run) across this bridge and continue all the way to the opposite end of this room. Throw the switch in here, which raises a bridge in the southern room in this area (F), which you will now enter at the end of this passageway. Run from the rising platform to this panel and enter the passage it reveals. As soon as you can get on the platform to ride it up, press a switch halfway up the northwest corner (you don't need to be level with the switch, just standing in front of its location and facing it) to open the gray granite panel at the end of the hallway. Turn your back to the nukage, drop in, and press the button in the center of the bulkhead in front of you, lowering the platform on your (the eastern) end. At the end of this hallway are entrances to two similar rooms, each with two platforms at either end, separated by a nukage pool in the middle (E). Leave this area by opening the face panel behind a partition in the northwest corner, and drop back into the entrance room.Įnter the now-accessible central area, and head for the doorway to the east (the one to your right as you enter), taking a long hallway bounded by fences on either side.

Pushing it will open the door leading into the central area (D). Pressing the face panel here reveals yet another lift, which you ride up to the eastern gallery which overlooked the entryway. Deal with the nasties, then move along the platform along the southern edge, reaching a passageway to the right. This will reveal a lift and a face panel in the other, eastern, room (C).Įnter the other room of the pair, push the face, and ride the lift down. Using the red keycard, first enter the western one (B). In the hallway just outside of the entry room and the room with the red keycard are two rooms each reached by a flight of stairs. If you center yourself just so in this corridor and aim carefully, you can run down the narrow, twisty, jagged bridge to the red keycard (A), pick it up, and be able to run backwards, without turning around, to make your escape before the monsters released are able to do you damage. Walk across the pathway over the nukage, passing through a doorway.
